A kind of cable precoated metal band described in any of the above-described embodiment, it is characterised in that the thickness of the base band
For 0.08~0.50mm.
A kind of cable precoated metal band described in any of the above-described embodiment, it is characterised in that the metal tape is steel
Band or aluminium strip.
A kind of cable precoated metal band described in any of the above-described embodiment, it is characterised in that the material of the coating layer
Expect for polyethylene or ethene-acrylic copolymer or polyester or polypropylene, or, the coating layer is by by weight
Made of following material:60~80 parts of polyethylene, 10~20 parts of polypropylene, 5~10 parts of two fat of phthalic acid fourth, epoxy resin

A kind of cable precoated metal band described in any of the above-described embodiment, it is characterised in that the thickness of the coating layer
Degree minimum value is 0.03mm.
In the present invention, due to the presence of the groove on base band surface so that coating layer can enter in groove so that coating layer
Stronger with the cohesive force of base band, during using covering material of the prior art, the adhesion strength between base band and coating layer is more than
12N/cm, after optical cable or cable is made, it is more than 8N/cm with the adhesion strength of sheath;6.13 N/cm in compared with prior art
And 3.6 N/cm compare, tool is greatly improved, thus into optical cable or cable, cohesive index is all qualified;Due to using field
Close and require different, some cables only need the adhesion strength of one side to increase, and some needs are two-sided all to be increased, the technology in the present invention
Scheme can meet the demand, the overlay film steel band and overlay film aluminium strip of applicant's production, be used through user, in terms of not having adhesion strength
Complaint and bad quality information feedback, therefore, applicant thinks that technical scheme has reached expected requirement, and
The present invention is easily fabricated, cost price increase is less.
In the present invention, using the overlay film layer material of inventive formulation, even if not using the reeded structure of tool, base band is with covering
Adhesion strength between film layer is more than 8.4N/cm, after optical cable or cable is made, is more than 6.1N/cm with the adhesion strength of sheath;
Using the reeded structure of tool, while after the overlay film layer material of the above-mentioned formula of use,
Adhesion strength between base band and coating layer is more than 12N/cm, after optical cable or cable is made, the bonding with sheath
Intensity is more than 14.3N/cm;After optical cable or cable is made, it is more than 12.6N/cm with the adhesion strength of sheath;Therefore, significantly
Improve the adhesion strength of overlay film aluminium strip and overlay film steel band.
In the present invention, metal tape is not only suitable for steel band or aluminium strip, similarly suitable for metal tapes such as copper strips, alloy strip.
The present invention is not limited to above-mentioned preferred forms, it will be appreciated that design of the invention can be by other a variety of shapes
Formula is implemented to use, and they are also fallen within protection scope of the present invention.
